Genes affected
ORC6 (HGNC:17151): (origin recognition complex subunit 6) The origin recognition complex (ORC) is a highly conserved six subunit protein complex essential for the initiation of the DNA replication in eukaryotic cells. Studies in yeast demonstrated that ORC binds specifically to origins of replication and serves as a platform for the assembly of additional initiation factors such as Cdc6 and Mcm proteins. The protein encoded by this gene is a subunit of the ORC complex. Gene silencing studies with small interfering RNA demonstrated that this protein plays an essential role in coordinating chromosome replication and segregation with cytokinesis. [provided by RefSeq, Oct 2010]
VPS35 (HGNC:13487): (VPS35 retromer complex component) This gene belongs to a group of vacuolar protein sorting (VPS) genes. The encoded protein is a component of a large multimeric complex, termed the retromer complex, involved in retrograde transport of proteins from endosomes to the trans-Golgi network. The close structural similarity between the yeast and human proteins that make up this complex suggests a similarity in function. Expression studies in yeast and mammalian cells indicate that this protein interacts directly with VPS35, which serves as the core of the retromer complex. [provided by RefSeq, Jul 2008]

ACMG classification

Classification was made for transcript

Our verdict: Uncertain_significance. The variant received 2 ACMG points.

PVS1
Start lost variant, next in-frame start position is after 3 pathogenic variants. Next in-frame start position is after 20 codons. Genomic position: 46689763. Lost 0.076 part of the original CDS.
PP5
Variant 16-46689707-T-C is Pathogenic according to our data. Variant chr16-46689707-T-C is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 253272.
BS1
Variant frequency is greater than expected in population nfe. GnomAd4 allele frequency = 0.000348 (53/152156) while in subpopulation NFE AF = 0.000662 (45/67980). AF 95% confidence interval is 0.000508. There are 0 homozygotes in GnomAd4. There are 23 alleles in the male GnomAd4 subpopulation. Median coverage is 33. This position passed quality control check. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting
